Egg allergy symptoms usually occur a few minutes to a few hours after eating eggs or foods containing eggs. Signs and symptoms range from mild to severe and can include skin rashes, hives, nasal inflammation, and vomiting or other digestive problems. Rarely, egg allergy can cause anaphylaxis -- a life-threatening reaction.

Egg allergy can occur as early as infancy. Most children outgrow their egg allergy before adolescence. But in some cases, it continues into adulthood.
